The Effect of Attendance on Grade for First Year Economics Students in University College Cork
This paper examines the relationship between attendance and grade, controlling for other factors, in first year economics courses in University College Cork. Determinants of both class attendance and grade are specified and estimated. We find that attendance is low, at least by comparison with US evidence. Hours worked and travel time are among the factors affecting class attendance. Class attendance, and especially tutorial attendance has a positive and diminishing marginal effect on grade, while hours worked in a part-time job have a significant negative effect on grade.
The Effects of Language Processing Strategies Upon Reading Comprehension
In 1975, the Education for All Handicapped Children Act was passed providing educational services for children with exceptionalities. Learning disabilities was one of those exceptionalities whose definition used a language disorder as its major criteria for the identification and classification of a specific learning disabilities. The inclusion of language disorders within its definition brought about greater interest in language and the understanding of language development, acquisition and processing and how these aspects related with academic learning, particularly with reading.
The purpose of this study was to address the issue of language processing strategies in the remediating of language deficits and to see if this remediation would have a direct effect upon language ability and/or reading comprehension. The population consisted of 18 children from rural east central Illinois whose ages ranges from 7 years, 2 months to 12 years, 10 months. Their education needs ranged from learning disabilities, educable mentally handicapped, remedial reading to tutorial help. The design of the study was pre-test/post-test control group experimental design. The two dependent variables were the reading comprehension scores and the language processing scores. The independent variable was a teacher-made language processing strategy program. The subjects were assigned to either the control or experimental group by using matched scaled scores from the reading comprehension pre-test.
The experimental subjects were exposed to the intervention for 15-minute periods for a total of sixteen days by trained university students from a special education practicum class. The control subjects were given instruction in various academic areas at the same time. At the end of the 3 week program, all subjects were post-tested in both reading comprehension and language processing and a t-test for related measures was performed using the gain scores between the pre- and post-test scores from the reading comprehension test and language processing test. Utilizing an alpha level of .05 with 8 df, no significance was found in either the reading comprehension (t=. 217) or the language processing ability (t=1.381). The results of the study indicate a need for further research in the area of language processing and its relationship with academic learning. No conclusive results were derived from this particular study
Family structure and breakfast consumption of 11-15 year old boys and girls in Scotland, 1994-2010
<p>Abstract</p> <p>Background</p> <p>The benefits of breakfast during childhood and adolescence have been reported previously though few studies have considered family structure inequalities in breakfast consumption. The proportion of young people living in non-traditional family types has increased in recent years, strengthening the need to describe and monitor the impact of the changing family unit on adolescent breakfast consumption. This study aimed to describe changes in daily breakfast consumption among adolescents in Scotland between 1994 and 2010, while also considering family structure inequalities, and the degree to which these have changed over time.</p> <p>Methods</p> <p>Data from the 1994, 1998, 2002, 2006 and 2010 Scottish Health Behaviour in School-aged Children (HBSC) surveys were analysed using logistic multilevel regression models for binary outcome variable daily breakfast consumption.</p> <p>Results</p> <p>Daily breakfast consumption among adolescents increased between 1994 and 2010, although there were differences by age and sex. In fact those aged over 14.5 years saw decreases in breakfast consumption, and girls saw significantly larger increases than boys. Daily breakfast consumption was more prevalent among adolescents from 'both parent' families, with lowest prevalence among those from single parent families. Trends in daily breakfast consumption between 1994 and 2010 also varied by family structure. While prevalence of daily breakfast consumption increased among those living with 'both parents', the largest proportion of the population, prevalence decreased over time among adolescents of single parent families, and particularly among those living with their father.</p> <p>Conclusions</p> <p>Family structure inequalities in daily breakfast consumption increased between 1994 and 2010, while breakfast consumption across the population as a whole increased. As the proportion of young people living in an alternative family structure continues to grow it is important to understand why these inequalities have increased and how these may be overcome. Possible reasons for family structure inequalities and their increase in recent years are discussed.</p
Does attendance affect grade? An analysis of first year economics students in Ireland
This paper examines the relationship between attendance and grade, controlling for other factors, in first year economics courses in University College Cork. Determinants of both class attendance and grade are specified and estimated. We find that attendance is low, at least by comparison with US evidence.

Class attendance, and especially tutorial attendance has a positive and diminishing marginal effect on grade, while hours worked in a part-time job have a significant negative effect on grade
Knowledge is power: general practitioners prescribing of new oral anticoagulants in Ireland
Objective: New oral anticoagulants (NOACs) aim to overcome warfarin’s shortcomings, however their pharmacokinetic characteristics make prescribing complex. Thus it is imperative that general practitioners (GPs) are aware of specific treatments so as to maximise their benefits and minimise their pitfalls. This study explores GPs attitudes and experiences with prescribing NOACs in Ireland where, despite clear national prescribing guidelines advocating warfarin as first line therapy, the number of patients being prescribed NOACs for the first time is growing. Results: Using primary data collected from GPs in Ireland the factors influencing the likelihood of a GP initiating a prescription for a NOAC are determined using a probit model. Results indicate 46% of the sample initiated NOAC prescriptions and GP practice size is a significant factor influencing this. Analysis revealed no difference regarding the sources of information considered important amongst GPs when prescribing new drugs. However, there were differences in which factors were considered important when prescribing anticoagulants between initiating and non-initiating NOAC prescribers. The results of this study suggest better utilisation of existing information and education tools for GPs prescribing NOACs and managing NOAC patients is imperative, to ensure the right anticoagulant is prescribed for the right patient at the right time
Profile of repeat victimisation within multi-agency referrals
To help reduce victimisation, safeguarding practices in England and Wales are becoming more
multi-agency, with Multi-Agency Safeguarding Hubs (MASH) being a contemporary example of
such an approach. MASH aims to reduce victimisation by identifying and managing vulnerability at
the earliest opportunity. This is achieved through the co-location of safeguarding agencies, joint
decision making and the co-ordination of interventions. Previous research has indicated that the
demand placed upon MASH often outweighs available resources, questioning the extent to which
MASH effectively safeguards vulnerable people at the earliest opportunity. Whilst existing literature
has focused upon the characteristics of MASH referrals, alongside referral processes, rates of
repeat referrals have been overlooked. This paper aims to bridge this gap by exploring the number
of repeat referrals made over a two-month period to a MASH location in the north-west of
England (n ¼ 2,134). By investigating repeat referrals, reasons why some individuals are susceptible
to being victimised on multiple occasions are identified. The paper concludes that whilst MASH has
taken a step towards identifying and managing victimisation, practices and processes need to be
reviewed if MASH is to proactively prevent repeat victimisation
Obesity, diet quality and absenteeism in a working population
The relationship between workplace absenteeism and adverse lifestyle factors (smoking, physical inactivity and poor dietary patterns) remains ambiguous. Reliance on self-reported absenteeism and obesity measures may contribute to this uncertainty. Using objective absenteeism and health status measures, the present study aimed to investigate what health status outcomes and lifestyle factors influence workplace absenteeism. Cross-sectional data were obtained from a complex workplace dietary intervention trial, the Food Choice at Work Study. Four multinational manufacturing workplaces in Cork, Republic of Ireland. Participants included 540 randomly selected employees from the four workplaces. Annual count absenteeism data were collected. Physical assessments included objective health status measures (BMI, midway waist circumference and blood pressure). FFQ measured diet quality from which DASH (Dietary Approaches to Stop Hypertension) scores were constructed. A zero-inflated negative binomial (zinb) regression model examined associations between health status outcomes, lifestyle characteristics and absenteeism. The mean number of absences was 2·5 (sd 4·5) d. After controlling for sociodemographic and lifestyle characteristics, the zinb model indicated that absenteeism was positively associated with central obesity, increasing expected absence rate by 72 %. Consuming a high-quality diet and engaging in moderate levels of physical activity were negatively associated with absenteeism and reduced expected frequency by 50 % and 36 %, respectively. Being in a managerial/supervisory position also reduced expected frequency by 50 %. To reduce absenteeism, workplace health promotion policies should incorporate recommendations designed to prevent and manage excess weight, improve diet quality and increase physical activity levels of employees
Monomeric structures of hexokinase I
Hexokinase I, the pacemaker of glycolysis in brain tissue, is composed of two structurally similar halves connected by an [Alpha]-helix. The enzyme dimerizes at elevated protein concentrations in solution and in crystal structures; however, almost all published data reflect the properties of a hexokinase I monomer in solution. Crystal structures of mutant forms of recombinant human hexokinase I, presented here, reveal the enzyme monomer for the first time. The mutant hexokinases bind both glucose 6-phosphate and glucose with high affinity to their N- and C-terminal halves, and ADP, also with high affinity, to a site near the N-terminus of the polypeptide chain. Exposure of the monomer crystals to ADP in the complete absence of glucose 6-phosphate reveals a second binding site for adenine nucleotides at the putative active site (C-half), with conformational changes extending 15 Ã… to the contact interface between the N- and C-halves. The structures reveal a flexible region of the C-half and a rigid-body rotation of the N-half, as possible elements of a structure-based mechanism for allosteric regulation of catalysis
